Babyberry Pie by Heather Vogel Frederick, illustrated by Amy Schwartz

From chapters.ca:
How do you bake a babyberry pie? Pick one wiggly baby from the babyberry tree. Pop him in the tub and scrub clean. Add sugar to his nose and toes. Tuck him into a warm pie crust. And don't forget a kiss goodnight! That's the perfect recipe for a babyberry pie - and a playful, peaceful bedtime. (Just don't let that little giggleberry wiggle away!)
